An earlier version of this story incorrectly stated that the St. Louis County Workforce Investment Board turned away 300,000 retraining applicants and that more than 9 million individuals participated in the program in 2010 in Missouri. Those numbers are for nationwide retraining programs supported by U.S. government funding.
